Aerosol Generation Device with Sleeve Cover

Abstract

The present invention relates to an aerosol generation device with a sleeve cover. More specifically, an aerosol generation device includes: an aerosol generation chamber configured to receive and heat a substrate to generate aerosol, wherein the aerosol generation chamber has an upper portion, a lower portion and an expansion mechanism; and a cover having a covering position and a non-covering position.

1 . An aerosol generation device comprising:
 an aerosol generation chamber configured to receive and heat a substrate to generate aerosol, wherein the aerosol generation chamber comprises an upper portion, a lower portion and an expansion mechanism, wherein the aerosol generation chamber is moveable between a closed state in which a surfaces of the upper portion and a surface of the lower portion substantially enclose a volume containing the substrate for consuming the substrate, and an open state in which the surface of the upper portion and the surface of the lower portion are distanced from each other by the expansion mechanism, so that the substrate can be received by or removed from the chamber; and   a cover having a covering position and a non-covering position; wherein when the cover is in the non-covering position, the volume inside the aerosol generation chamber is exposed and the aerosol generation chamber is in the open state, and when the cover is in the covering position, the aerosol generation chamber is covered by the cover and is in the closed state.   
     
     
         2 . The aerosol generation device according to the  claim 1 , wherein the expansion mechanism is configured with repelling magnets, springs, or a clip providing an expansion force so as to distance the surface of the upper portion from the surface of the lower portion when the cover is moved from covering position to the non-covering position. 
     
     
         3 . The aerosol generation device according to  claim 1 , wherein the cover is engaged with the upper portion so as to transition the aerosol generation chamber from the open state to the closed state or vice versa when the cover moves from the covering position to the non-covering position or vice versa. 
     
     
         4 . The aerosol generation device according to  claim 3 , wherein the cover is configured to slide on a main body of the aerosol generation device and is slidingly engaged with the upper portion of the aerosol generation chamber, so that the cover is configured to press down the upper portion or release the upper portion so as to bring the upper portion closer to the lower portion or distance the upper portion from the lower portion via the expansion mechanism when sliding on the main body. 
     
     
         5 . The aerosol generation device according to  claim 4 , wherein an upper surface of the upper portion is configured to connect with the cover, and the upper surface is an inclined and/or curved surface, so that the upper portion is configured to be pressed down so as to substantially enclose the substrate by the cover in the covering position, and is configured to be released from the pressure of the cover through sliding the cover to its non-covering position. 
     
     
         6 . The aerosol generation device according to  claim 1 , wherein the expansion mechanism comprises a spring steel framework arranged between the upper portion and the lower portion, which is configured to receive and hold the substrate. 
     
     
         7 . The aerosol generation device according to  claim 6 , wherein the spring steel framework comprises an ejection plate configured to at least partially push the substrate out of the aerosol generation chamber when the aerosol generation chamber is opened. 
     
     
         8 . The aerosol generation device according to  claim 6 , wherein the spring steel framework is made of a steel frame or plate having a predetermined angle, and is configured to be compressed by an outer force. 
     
     
         9 . The aerosol generation device according to  claim 1 , wherein the aerosol generation chamber comprises heating elements on the upper portion and/or the lower portion, for heating the substrate. 
     
     
         10 . The aerosol generation device according to  claim 9 , wherein an attaching surface of the spring steel framework is attached to the upper portion, and a holding surface of the spring steel framework for holding the substrate is arranged opposite to the attaching surface, so that the holding surface is able to be sprung away from the heating element of the upper portion when the aerosol generation chamber is opened. 
     
     
         11 . The aerosol generation device according to  claim 7 , wherein the ejection plate forms a leaf or flat spring attached with the steel spring framework, so as to push the substrate from the steel spring framework. 
     
     
         12 . The aerosol generation device according to  claim 6 , wherein the spring steel framework is slidingly attached to the upper portion so that the spring steel framework is removable from the aerosol generation chamber. 
     
     
         13 . The aerosol generation device according to  claim 1 , wherein the lower portion and/or the upper portion are rotationally hinged in the device. 
     
     
         14 . The aerosol generation device according to  claim 1 , wherein the cover comprises a limiting portion for pushing the substrate into the aerosol generation chamber and fully maintaining the substrate in the aerosol generation chamber. 
     
     
         15 . The aerosol generation device according to  claim 1 , wherein the substrate is compressed when the aerosol generation chamber is in the closed state.
